74AUP1T34
Low-power dual supply translating buffer
Rev. 5 â 4 September 2013
Product data sheet
1. General description
The 74AUP1T34 provides a single buffer with two separate supply voltages. Input A is
designed to track VCC(A). Output Y is designed to track VCC(Y). Both, VCC(A) and VCC(Y)
accepts any supply voltage from 1.1 V to 3.6 V. This feature allows universal low voltage
interfacing between any of the 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V voltage nodes.
Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall
times across the entire VCC range from 1.1 V to 3.6 V. This device ensures a very low
static and dynamic power consumption across the entire VCC range from 1.1 V to 3.6 V.
This device is fully specified for partial power-down applications using IOFF.
The IOFF circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
